Sometimes, the stack a developer knows makes them feel stuck in place. Or maybe a person’s knowledge is limited to just one layer, or one technology. This makes the decision to learn something new an easy one, but choosing what to learn can be a difficult process. Information is everywhere, but it can seem disparate, contradicting, or biased. In this limited run of Compiler, we speak to people within development teams and communities to bring clarity to the tech stack. We explore how it all comes together to make the applications we use, and how pushing beyond one layer can open up exciting possibilities.
